[quote=klozhald][quote=Klozhald]The downside is stuffing a hull and doing a face plant in the very materal from which they make 40 grit sandpaper.[/quote]
[quote=mn3]It is my understanding that sand is not used in sandpaper.
Materials used for the abrading particles are:
flint: no longer commonly used
garnet: commonly used in woodworking
emery: commonly used to abrade or polish metal
aluminium oxide: The most common in widest variety of grits, lowest unit cost; can be used on metal (i.e. body shops) or wood
silicon carbide: available in very coarse grits all the way through to microgrits, common in wet applications
alumina-zirconia: (an aluminium oxide–zirconium oxide alloy), used for machine grinding applications
Chromium(III) oxide: used in extremely fine micron grit (micrometre level) papers
ceramic aluminum oxide: used in high pressure applications, used in both coated abrasives, as well as in bonded abrasives [/quote]
It was a joke, but thanks for the information. :/[/quote]
